1 Important information/Safety regulations

 

These instructions are a UK-specific appendix to those instructions found in the Installation instructions.

 

Read the Installation instructions prior to installation.

 

For DHP Opti Pro SP (Single Phase) heat pumps it is imperative that the maximum hot water temperature

is altered from the default factory setting from 95°C to 60°C. Refer to Chapter 9.8 menu Service – HGW

Parameter MAX TEMP in Installation instructions.

 

Hard Water Areas; Normally it is not a problem to install a heat pump in hard water areas since the normal

domestic hot water working temperature will be not greater than 60°C. In areas where exceptional water

conditions prevail, consideration may need to be given to the fitting of a device capable of inhibiting scale.

In such circumstances the advice of the local water authority should be sought.

 

The immersion heater, thermostat, and thermal cut-out are supplied by Danfoss and are factory fitted. If a

replacement part is necessary, it must be replaced with a Danfoss spare part.

 

The water heater is protected with a sacrificial aluminium anode. Under normal circumstances no mainte-

nance is needed.

 

Note! Leave the following documents with the end-user;

- This manual

- Installation instructions

- User manual

The above documents are an integral and essential part of the product. They should be kept with the appli-

ance so that they can be consulted by the user and our authorised personnel.

Please read carefully the instructions and notices about the appliance contained in this manual, as they pro-

vide important information regarding the safe installation, use and maintenance of the heat pump.

1.1 Test results

1.1.1 Heat up time

The heat up time is measured when heating the water from 14°C to 60°C.

DWH 300: Heat up time 1 hour 53 minutes

DHP-H, DHP-A, DHP-AQ Maxi and DWH 200: Heat up time 1 hour 3 minutes

1.1.2 Re-heat time

The re-heat time is measured when 70% of the hot water has been drained and replaced by equal amount

14°C water and re-heated to 60°C.

DWH 300: Re-heat times 70% 1 hour 25 minutes

DHP-H, DHP-A and DWH 200: Re-heat time 70% 41 minutes

DHP-AQ Maxi: 1 hour 6 minutes according to EN12897.

1.1.3 Pressure drop

The measured pressure drop throgh the primary heater is 15 kPa.

1.1.4 Hot water capacity

DHP-AQ Maxi: 160 liter according to EN12897.
